NPT pipe threads

NPT pipe threads

Please add NPT pipe threads to the thread options in the thread dialog box. Tnx!

I'd have to agree. It is pretty darned sad that this hasn't been added.

Aww come on guys but aren't you excited that this last updated they brought improvements to texture mapping so you can have better control over the orientation of your brushed finish appearance? That is way more important than NPT threads.

but... but... I need to draw the threads before rendering them, not render the images in my head!

 They have everything else so the U.S. must not matter!

Honestly NPT is probably the most common tapered thread internationally at this point. I love how surprised AD seemed in the beginning of this thread when someone asked for it like the OP must be a plumber or something but NPT is used a lot.
Then there are ISO pipe threads which somehow insanely stupidly are Whitworth standard pipe threads. These are almost identical to NPT but just enough different to not be compatible. They are also rated in inches wheras in F360 the ISO pipe threads are rated in mm making it very difficult to figure out if they are actually Whitworth or something else. Whatever the case though F360 still only offers straight ISO pipe threads and not tapered which are just as important as straight and NPT tapered. Sure you could model straight and then just call out the tapered thread in drawings which is fine since we have to do hole and thread callouts manually still anyway. In that situation I select BSP pipe threads in the dropdown because it is the only one that calls out in fractional dimensions like NPT. Then you have a straight thread modeled in what should be the right approx size and you just call it out for the NPT thread you want in the drawing.

Making tapered threads should be insanely easy for AD to do. Since all tapered threads have a nominal depth you really just need a plug the right shape that you could use like the hole wizard using a round surface or point that you would use as the base reference point and it would make a cutout at the nominal depth based off that reference point. A depth adjustment you could set manually would be very handy for making small tweaks or for tapping on non flat surfaces.
Until AD gets done with important things like improving surface textures the best solution is to find your own NPT plugs that you can do material cuts with if you need actual tapered threads of any type.

Three years later and still no NPT - was just working on a part today and I need it for that part! Welp back to Inventor 2015 I guess. Might as well just buy the inventor subscription instead of the Fusion one. We use the free Fusion license so I'll go back to drawing parts in Inventor and just using Fusion for CAM.

"fully featured" would include this 5 years ago

One would think they would have along with a few other things that should have been added last year .

It has always been possible to cut tapered threads with the thread toolpath in HSMWorks, InventorHSM, and Fusion. The workflow is the same as threadmilling straight threads. The hole needs to be accurately modeled with the diameter, depth, and taper angle, and then the toolpath will follow the taper of the face to cut the thread.

 

I had mistakenly posted in this thread thinking I was in the CAM Ideastation. My mistake!

An update on the NPT request:

  • This will be a part of Hole / Thread enhancement project.
  • The team is finishing the design of the user interaction.
  • Thread improvements is prioritized to be done once project that the team is currently working on is complete.

i have literally given up, we do the NPT on the old hand powered drill
press with an automatic reverse thingy that i hear they don't even make
anymore...

but the rest of the gcode is great

i tried doing some other fixes people gave, my machine only does 2 axis
simultaneous movement...

Any word on the NPT threads? Pretty unbelievable that it's not a standard. Tinkercad even has NPT pipe threads of various sizes. And it's a lot more user-friendly than fusion 360.

While I don't need NPT threads very often, it's critical for one of my ongoing projects.

I've modelled them using the coil feature (outside triangle), then create the thread profile on a perpendicular plane and sweep the shape along the outer rail generated by the coil. It's a bit of a pain to look everything up and model it, but it seems to work. From now on I intend to recycle this geometry any time I need an NPT thread.

I have seen many work around to getting this to work, including importing mcmaster carr plugs and doing a subtraction of that body... but seriously, we are all engineers here (that means we are lazy and want the fastest solution). Is there some arithmetic or spreadsheet of dimensions and data that you'd like me to build to accelerate this process.

I'm just subscribing to this thread. I could really use this. It's kind of amazing that NPT sizes are not already in fusion.

Any guesses how long it will be before we see NPT threads. I still find it hard to believe that they are not here yet. I build LOTS of stuff with NPT threads. I work in a wastewater treatment plant. There are pipe threads on almost everything I have to build. Come on guys, we NEED THIS.

you would think they have gotten the hint by now with all the complaints, but sadly no one there cares from the looks of things. clearly being professional about it not working.

Currently working on a project that utilizes 1/4 - 18 NPT, this cannot be added fast enough 😕
